[0039] The following description provides many different embodiments or examples for implementing different features of the present application. The components and arrangements described in the following specific examples are only used to simplify the present application and are only examples, not to limit the present application.

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for which protection is claimed, but merely represents selected embodiments of the present application.

[0041] In this application, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," and the like should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal connectivity between two elements or an interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood based on the specific circumstances. In addition, the terms "first," "second," "third," and the like are used only to distinguish descriptions and are not to be understood as indicating or implying relative importance.

[0042] In this application, unless otherwise expressly specified or limited, a first feature being above or below a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being above, above, and above a second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being below, below, and below a second feature includes the first feature being directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0043] However, existing guardrails are composed of multiple guardrail units, fixedly mounted on upright posts, with adjacent guardrail units connected via splices, springs, and other means. After being struck by a vehicle, the guardrail's energy absorption is poor. The distance between adjacent guardrail units increases due to the greater impact force, and the units can even become detached from each other, making it difficult or impossible for the guardrail assembly to return to its initial state. Furthermore, existing guardrails have high contact stiffness, causing significant damage to vehicles. Furthermore, the guardrail device has a single energy absorption mode and limited buffering effect, making it impossible for the guardrail to recover after an impact and resulting in high maintenance and replacement costs.

[0044] It should be noted that the vehicles in this application can be individual types such as cars, trucks, buses, trailers, incomplete vehicles, motorcycles, etc., and are not limited here.

[0045] In view of this, the application provides a traffic crash barrier device, as shown in the accompanying drawings, comprising: Figures 1-13

[0046] A post assembly 10, the post assembly 10 comprising a post 11 and a mounting base 12, the post 11 being rotatably mounted to the mounting base 12.

[0047] For example, the mounting base 12 is fixedly arranged on the ground on both sides of the road, and at least two mounting bases 12 are arranged at intervals on the same side of the road. The mounting base 12 is a hollow structure, and the end of the mounting base 12 away from the ground has an opening, and the lower end of the post 11 is mounted into the mounting base 12 through the opening. When the impact force is transmitted to the post 11 after the vehicle hits the barrier assembly 10, the post 11 can be tilted relative to the mounting base 12, and the direction of the tilt is in the y direction away from the barrier assembly 20. On the one hand, the impact of the vehicle can be better reduced to avoid the situation that the vehicle is blocked by the post 11 during the collision; on the other hand, more posts 11 and barrier units 21 are involved in the collision process, and the cooperative energy dissipation effect is better.

[0048] In some optional embodiments, the post 11 can be movably mounted in the mounting base 12 by means of insertion. By means of insertion, the post 11 and the mounting base 12 can be assembled and disassembled, and the assembly efficiency is improved. For example, the lower end of the post 11 is provided with a rotating groove 41, the rotating groove 41 penetrates the post 11 in the extension direction (x direction) of the barrier assembly 20, and the mounting base 12 is fixedly provided with a rotating shaft 40 in the x direction. The post 11 is inserted into the rotating shaft 40 in the mounting base 12 through the rotating groove 41, so as to realize the rotation and tilt of the post 11 relative to the mounting base 12.

[0049] In some optional embodiments, the post 11 is movably mounted in the mounting base 12 by means of a pin 19. For example, the lower end of the post 11 is provided with a through hole in the x direction, and the post 11 and the mounting base 12 are connected by means of the pin 19 penetrating the through hole, so as to realize the stable connection of the post 11 and the mounting base 12.

[0050] In some optional embodiments, the mounting base 12 is provided with a limiting hole 121 on each side, and the limiting hole 121 extends in the y direction. When the post 11 is inserted into the mounting base 12, the post 11 and the mounting base 12 are connected by means of a bolt 18 penetrating the limiting hole 121, and the bolt 18 can slide in the limiting hole 121. After the post 11 is impacted, the post 11 is tilted backward along the limiting hole 121 by means of the bolt 18. The length of the limiting hole 121 limits the tilt angle of the post 11, thereby controlling and adjusting the overall deformation degree of the barrier assembly 20, and realizing the effective energy absorption of the barrier assembly 20.

[0051] ​Preferably, the pillar 11 is in a rod-like, column-like or other shape, which is not limited here.

[0052] The guardrail assembly 20 extends in the x-direction, with both ends of the guardrail assembly 20 correspondingly mounted to the pillar assembly 10. For example, both ends of the guardrail assembly 20 in the x-direction are movably mounted to the pillar 11, with the guardrail assembly 20 mounted on the side of the pillar 11 facing the lane to provide energy absorption protection against vehicles approaching in the lane.

[0053] The guardrail assembly 20 includes multiple guardrail units 21, such as two, three, or four guardrail units 21, each connected by a first spring 22. For example, each guardrail unit 20 is provided with a connector 27 at each end, and each end of the first spring 22 is fixedly connected to the connector 27 on the corresponding guardrail unit 20. After a guardrail unit 21 or the first spring 22 is impacted, the first spring 22 is in a pull-cord state, increasing the overall length of the guardrail assembly 20.

[0054] There are at least two resistance members 23 in each guardrail unit 21, and there can be two, three, four, etc. resistance members 23. The resistance members 23 can be in the shape of a resistance ball, a resistance block, etc., and the present application prefers a resistance ball. The resistance members 23 in two adjacent guardrail units 21 are connected by at least one traction rope 24, and a threading hole 271 is provided on the connector 27. The two ends of the traction rope 24 pass through the corresponding threading holes 271 to be connected to the resistance members 23, and the traction rope 24 passes through the first spring 22. In some optional embodiments, when there are two resistance members 23 in a guardrail unit 21, the two resistance members 23 are respectively connected to the traction rope 24 on the corresponding side. The two resistance members 23 may be connected or not connected, and there is no limitation here. Optionally, the traction rope 24 may be a steel wire rope.

[0055] After the guardrail assembly 20 is hit, the first spring 22 can achieve limited stretching under the action of the traction rope 24 and the resistance member 23. For example, when the guardrail assembly 20 is hit by an out-of-control vehicle, on the one hand, the first spring 22 is deformed and stretched under the force, so that the length of the guardrail assembly 20 becomes longer, and the guardrail units 20 are not easy to break, so that more impact force can be absorbed. The guardrail assembly 20 becomes an arc after being hit. Under the guidance and anti-impact force of the arc, the vehicle can be guided back to the lane, avoiding the vehicle from getting stuck in it after hitting the guardrail assembly 20, or rushing in the opposite direction to other lanes. On the other hand, the traction rope 24 is pulled by force to move the resistance members 23 at both ends in the corresponding guardrail unit 21, buffering the force and stretching speed of the first spring 22. When the resistance member 23 moves to abut the inner wall of the connector 27, it becomes immobile, maximizing the distance between the traction rope 24 and the first spring 22. This minimizes the deformation of the first spring 22. Specifically, the traction rope 24 and the resistance member 23 limit the extent to which the first spring 22 pulls, allowing the guardrail assembly 20 to return to its initial state under the action of the first spring 22. For example, the length of the traction rope 24 is equal to or less than the deformation threshold of the first spring 22. This prevents the first spring 22 from excessively deforming under load, which could lead to the guardrail assembly 20 breaking and becoming unable to return to its original position.

[0056] Therefore, the traffic anti-collision guardrail device provided by the present application comprises a guardrail assembly 20 including a plurality of guardrail units 21, each guardrail unit 21 having a resistance member 23. Adjacent guardrail units 21 are connected by a first spring 22, and the resistance members 23 in the adjacent guardrail units 21 are connected by a traction rope 24. When impacted, the guardrail assembly 20 increases in length under the action of the first spring 22, absorbing more energy. At the same time, the traction rope 24 drives the resistance member 23 to move in a direction toward the first spring 22. The resistance member 23 becomes immobile when it abuts the inner wall of the connector 27. At the same time, the traction rope 24 is in a stretched state, thereby limiting the deformation of the first spring 22, so that the guardrail assembly 20 does not break and can be restored to its initial state.

[0057] According to some optional embodiments, two adjacent resistance members 23 in each guardrail unit 21 are connected by a second spring 25 , and the resistance members 23 can reciprocate along the extension direction of the guardrail unit 21 .

[0058] In the above solution, the resistance members 23 can be made of a relatively heavy metal material. Adjacent resistance members 23 are connected by a second spring 25, and adjacent resistance members 23 between adjacent guardrail units 21 are connected by a traction rope 24. When the guardrail assembly 20 is impacted, the traction rope 24 pulls the resistance members 23 at both ends toward each other. Since the adjacent resistance members 23 in each guardrail unit 21 are connected by the second spring 25, the speed at which the resistance members 23 are pulled by the traction rope 24 is slowed, increasing the traction force of the traction rope 24 pulling on the resistance members 23, thereby absorbing the impact force. At the same time, under the action of the second spring 25, the resistance members 23, traction rope 24, first spring 22, and guardrail unit 21 can be driven to return to their initial state.

[0059] According to some optional embodiments, the guardrail unit 21 is filled with a resistance material 26 , and the resistance member 23 is frictionally engaged with the resistance material 26 .

[0060] In the above solution, the resistance material 26 is a material, such as sand or ceramsite, that increases friction with the resistance member 23 during movement. For example, as the resistance member 23 moves under the traction of the traction rope 24, friction is generated between the resistance member 23 and the resistance material 26 during movement, slowing down the movement of the resistance member 23 and the traction force of the traction rope 24 on the resistance member 23, thereby increasing energy consumption.

[0061] According to some optional embodiments, at least one feed port 211 and one discharge port 212 are provided on the side wall of the guardrail unit 21 . The feed port 211 is used to load the resistance material 26 into the guardrail unit 21 , and the discharge port 212 is used to discharge the resistance material 26 in the guardrail unit 21 .

[0062] In the above solution, at least one feed port 211 is provided at the top of the guardrail unit 21. The feed port 211 is preferably located near the ends of the guardrail unit 21. This is because the resistance balls 23 in the guardrail unit 21 will move toward the ends of the guardrail unit 21 under the traction of the traction rope 24. By loading the resistance material 26 at the end feed port 211, the resistance element 23 can be smoothly restored to its initial state. If the resistance material 26 is loaded in the middle, it will prevent the resistance element 23 from returning to its initial state. Similarly, the discharge port 212 is provided at the bottom of the guardrail unit 21, and is preferably located in the middle of the guardrail unit 21. This is because the resistance balls 23 in the guardrail unit 21 will move toward the ends of the guardrail unit 21 under the traction of the traction rope 24, and the resistance material 26 will be pushed to the middle of the guardrail unit 21. In this way, the resistance material 26 can be quickly discharged and the resistance element 23 can be quickly reset.

[0063] According to some optional embodiments, a first energy absorbing body 13 is further installed in the mounting seat 12 . The first energy absorbing body 13 is located on one side of the column 11 , and one end of the first energy absorbing body 13 is connected to the column 11 , and the other end is fixedly connected to the mounting seat 12 .

[0064] In the above embodiment, the first energy absorber 13 can be a spring, or an energy-absorbing material such as sponge, foam, or polyurethane foam. The first energy absorber 13 is located behind the pillar 11 and is in close proximity to the pillar 11. When the pillar 11 is impacted, it tilts backward, squeezing the first energy absorber 13 and deforming it. The first energy absorber 13 absorbs the energy of the vehicle impacting the guardrail assembly 20 and the pillar 11 through deformation. Furthermore, the first energy absorber 13 provides support for the pillar 11 during its tilting process, thereby reducing damage to the pillar 11 and the guardrail assembly 20.

[0065] According to some optional embodiments, a first cam 14 is fixedly provided on the outer wall of the column 11 located in the mounting seat 12, and the first cam 14 has a first abutting plane 141 and a first abutting arc surface 142 on the side away from the column 11, the first abutting plane 141 is located at the lower part of the first cam 14, and the first abutting plane 141 is an inclined surface; a second cam 15 is provided at the corresponding position of the first energy absorbing body 13, and the second cam 15 has a second abutting plane 151 and a second abutting arc surface 152 on the side adjacent to the first cam 14, the first abutting plane 141 and the second abutting plane 151 abut and cooperate to drive the first energy absorbing body 13 to slide horizontally along the mounting seat 12, and as the column 11 tilts, the first abutting arc surface 142 and the second abutting plane 151 abut and cooperate to drive the first energy absorbing body 13 to slide in the horizontal direction of the mounting seat 12, that is, slide in the y direction.

[0066] In the above embodiment, the first cam 14 and the second cam 15 have the same structure. The coordinated arrangement of the first cam 14 and the second cam 15 converts the rotation of the column 11 relative to the mounting base 12 into horizontal sliding movement of the first energy absorber 13. Furthermore, the coordinated arrangement of the first cam 14 and the second cam 15 provides a certain degree of support for the column 11. For example, when a vehicle loses control, it will first hit the guardrail assembly 20, and the guardrail assembly 20 will transmit the impact force to the column 11. Since the first cam 14 and the second cam 15 are cooperated on one side of the column 11, the specific first abutment plane 141 and the second abutment plane 151 abut, which can provide a larger supporting force for the column 11. Therefore, when the impact force transmitted to the column 11 is less than the preset value, the column 11 will not tilt easily, reducing the number of times the column 11 tilts and extending the service life of the column 11; when the impact force transmitted to 11 is greater than the preset value, the column 11 tilts, and with the cooperation of the first cam 14 and the second cam 15, the impact force is transmitted to the first energy absorbing body 13, and drives the first energy absorbing body 13 to move along the y direction, absorbing energy through compression.

[0067] According to some optional embodiments, the first energy absorbing body 13 includes a sliding member 131 and an energy absorbing member 132, the second cam 15 is fixedly installed on one side of the sliding member 131, the other side of the sliding member 131 is fixedly connected to the energy absorbing member 132, and the side wall of the sliding member 131 is slidably matched with the inner wall of the mounting seat 12.

[0068] Exemplarily, the sliding member 131 is located between the second cam 15 and the energy absorbing member 132, and the sliding member 131 is fixedly connected to the second cam 15 and the energy absorbing member 132 by bolt connection, welding, etc. The energy absorbing member 132 is detachably connected to the inner wall of the mounting seat 12 by bolts, clamping, etc. The sliding member 131 can slide horizontally relative to the inner wall of the mounting seat 12, thereby driving the energy absorbing member 132 to move horizontally. In some optional embodiments, sliding protrusions are provided on both side walls and the bottom wall of the mounting seat 12, and sliding grooves are provided at corresponding positions on the side walls of the sliding member 131. Through the sliding cooperation between the sliding protrusions and the sliding grooves, the sliding member 131 can slide relative to the inner wall of the mounting seat 12, and the cooperation between the sliding protrusions and the sliding grooves prevents the energy absorbing member 132 from shaking, so that the impact force can only be transmitted to the energy absorbing member 132 along the sliding direction, thereby greatly improving the energy absorption effect.

[0069] According to some optional embodiments, the energy absorbing member 132 includes a first shell 1321 and a second shell 1322. The first shell 1321 and the second shell 1322 are nested together to form an energy absorbing space. A first energy absorbing material 1323 is installed in the energy absorbing space. The first energy absorbing material 1323 can be a plurality of damping springs, foam, or other energy absorbing materials. The first shell 1321 can move relative to the second shell 1322, thereby compressing the first energy absorbing material 1323. The nested arrangement of the first shell 1321 and the second shell 1322 allows relative movement when subjected to an impact force, reducing the energy absorbing space and compressing the first energy absorbing material 1323. This prevents the first energy absorbing material 1323 from shaking when squeezed, thereby improving the energy absorption effect. Furthermore, the loading and replacement of the first energy absorbing material 1323 is facilitated.

[0070] According to some optional embodiments, the guardrail unit 21 is connected to the column 11 via a mounting member 30 , and the column 11 is provided with a receiving groove 16 , in which a second energy absorbing body 161 is installed, and the second energy absorbing body 161 abuts against the mounting member 30 .

[0071] In the above embodiment, a fixing seat 50 is provided on the column 11, and the mounting member 30 is movably connected to the fixing seat 50, and the guardrail assembly 20 is fixedly connected to the mounting member 30. A receiving slot 16 is defined in the mounting seat 50, located between the column 11 and the mounting member 30. The receiving slot 16 contains a second energy absorber 161, which can be a spring, foam, rubber, or the like. When squeezed by the mounting member 30, the second energy absorber 161 compresses and absorbs energy. When the guardrail unit 21 is impacted, the mounting member 30 can move in the y-direction, squeezing the second energy absorber 161 to absorb energy and reduce damage to the guardrail assembly 20.

[0072] According to some optional embodiments, the mounting member 30 is slidably connected to the column 11, wherein: the mounting member 30 is provided with a sliding hole 31, which is a bar-shaped hole and extends along the direction of the impact on the guardrail unit 21, and the extension direction of the sliding hole 31 is the y-direction. The column 11 slides with the sliding hole 31 through a connecting member 17, and the connecting member 17 is a pin. Exemplarily, the fixing seat 50 is fixedly mounted on the column 11, and the connecting member 17 passes through the sliding hole 31 to slidably connect the fixing seat 50 with the mounting seat 30. When the guardrail assembly 20 is impacted, the guardrail unit 21 pushes the mounting member 30 to move relative to the connecting member 17 in the y-direction, and the mounting member 30 compresses the second energy absorber 161, which absorbs energy and reduces damage to the guardrail unit 21.

[0073] The working principle of an out-of-control vehicle when colliding with a guardrail device: First, it collides with the guardrail assembly 20, and the first spring 22 between the guardrail units 21 is deformed by force. As the first spring 22 is deformed and stretched, the traction rope 24 is pulled by force to pull the resistance member 23 to move in the resistance material 26, and the resistance member 23 absorbs energy through friction with the resistance material 26. At the same time, the guardrail assembly 20 moves in the y direction after being subjected to force, squeezing the second energy-absorbing body 161, and the second energy-absorbing body 161 absorbs energy elastically; the impact force is transmitted to the column 11 through the second energy-absorbing body 161, causing the column 11 to tilt in the y direction, and the first cam 14 and the second cam 15 cooperate to convert the rotation of the column 11 into horizontal movement of the sliding member 131; the sliding member 131 moves along the y direction, squeezing the first energy-absorbing body 13, and the second energy-absorbing body 13 absorbs energy by compression. Because the resistance member 23 and the traction rope 24 limit the limited stretch of the first spring 22, after the vehicle impact, the first carbon spring 22 connected between the guardrail units 21 remains within the deformation range, while simultaneously releasing energy with the first energy absorber 13 and the second energy absorber 16, and the guardrail device returns to its initial state. This application adopts a multi-stage coordinated energy dissipation design structure to achieve a gradual reduction in vehicle collision energy, reduce the contact stiffness between the vehicle and the guardrail, and minimize vehicle damage.
